Floor waxer and polishing machine



March 7, 1950 P. H. CHAPPELL FLOOR WAXER AND POLISHING MACHINE Filed 001;. 20, 1948 PAUL H. CHAPPELL FIG. 2

Patented Mar. 7, 1950 UNITED STATES PATENT OFFICE 4 Claims. 1

My invention particularly relates to household appliances such as floor waxes, polishers, sanders and the like, which comprise a flat shoe adapted to be slid upon a flat surface and which shoe is covered by a suitable material such as wool, cheesecloth, sandpaper or similar strips of material, and my invention resides in providing a household appliance of this character in which the coverings for the shoe may be readily removed and securely fastened in position thereon.

It is therefore the principal object of this invention to provide a floor waxer in which the base thereof is formed primarily in two sections, one section forming a shoe to which the floor waxing or polishing fabric is secured and an upper base portion or casing which is removable from the shoe but is adapted to be securely fastened against the upper periphery thereof so as to engage and compress the ends of the fabric or other material therebetween and thereby securely fasten the fabric or the like to the face of the shoe. Another object resides in providing a floor waxer of the foregoing character in which the means for clamping the shoe portion and the upper portion of the base structure together serves the additional function of providing a bearing for a shaft by means of which the plunger in the wax reservoir formed in the shoe portion is actuated to force the wax outwardly through openings provided therefor in the shoe.

With the foregoing objects in view my invention includes the novel elements and the combinations and arrangements thereof described below and illustrated in the accompanying drawings, in which:

Fig. 1 is a, perspective view, partially broken away, of a preferred form of my invention; Fig. 2 is a sectional view of the floor polisher and waxer of Fig. 1 taken longitudinally thereof or in about the plane 2-2 of Fig. l; and Fig. 3 is a fragmentary sectional view taken transversely of the machine and through the wax reservoir.

It will be understood that the present inven tion is designed to rest upon a floor or other flat surface and to be moved about in such manner as to distribute wax thereover while the operator walks about the floor. Therefore, it is desirable that the casing of the machine be of substantial weight, and it is also desirable that the pressure exerted upon the wax in the reservoir may be readily regulated and positively secured. Hence, the machine of the present invention comprises a base which is formed of two parts, one part thereof comprising a shoe l which is preferably of substantial thickness and mass and has a cylinder 2 upstanding therefrom and preferably formed integral therewith. The other portion of the base comprises a casing 3 which is preferably of substantial weight and at the bottom thereof conforms generally in configuration to that of the shoe l, the lower and peripheral edge of the casing 3 being designed to fit within a rib 4 which extends peripherally of the shoe 1.

The cylinder 2 is internally threaded as indicated at 5 and forms a reservoir for wax or other fluid substances, and a piston 6 is provided with a threaded periphery adapted. to engage the threaded interior of the reservoir. One or a plurality of openings 1 are provided in the shoe 1 at the base of the reservoir through which the wax or other substance may flow to the material or fabric surrounding the shoe. For wax distribution purposes, a strip of felt 8 is preferably secured against the shoe, and for polishing purposes a strip of wool 9, cheesecloth or other suitable fiocculent material is secured to overlie the felt. Sandpaper may be substituted for the outer strip depending upon the needs of the user.

Preferably, the inner felt strip is secured to the face of the shoe by any suitable adhesive, while the outer strip is removably secured thereto by the casing 3, as above described.

In order to clamp the material 9 securely between the shoe and casing 3, I preferably provide an opening in the upper part of the casing which is sufficiently larger in diameter than the exterior of the reservoir as to permit the flange of a cover to extend therebetween, as clearly shown in Fig. 2. The outer and upper end of the reservoir 2 is screw-threaded as indicated at It and the interiorly threaded flange of a screw cap ll is adapted to engage the exterior threads of the reservoir so that the outer shoulder 82 of the screw cap will engage the casing 3 and thereby effect a compression of the material 9 between the casing and the shoe. The cap has wings 22 formed thereon to facilitate manual manipulation thereof.

The screw cap H is provided with a central opening i3 therein through which the upper cylindrical end of a shaft or piston rod is adapted to extend. The lower polygonal section 14 of the shaft passes through an opening in the piston 6 of like configuration so as to impart rotary movedrical portion l 3 of the shaft by means of a pin [8 passing through the shank of the handle and through a transverse passage in the cylindrical end [3 of the shaft.

Spaced, parallelly extending flanges i9 may be formed on the exterior of th casing 3 to which a suitable handle 20 may be pivotally secured as shown in Fig. 1.

By the construction above described, it will be noted that coverings for the shoe of the machine may be readily removed and yet easily but positively secured thereto. At the same time, the screw cap which is employed to effect a secure application of the shoe covering to the shoe serves not only to close the upper end of the-wax reservoir but also serves as a bearing for the handle actuated shaft or piston rod by means of which the wax in the reservoir may be placed under,

pressure and thereby forced through the openings in the shoe to maintain the cloth covering the same in fairly well saturated condition.

While I have described my invention in its preferred embodiments, it is to be understood that the words which I have used are words of description rather than of limitation and that changes within the purview of the appended claims may be made without departing from the true scope and spirit of my invention in its broader aspects.
